pippa middleton sunbathing
 Pippa Middleton sunbathing bikini photos have remained a hot topic since the royal wedding of her sister Kate Middleton (Duchess of Cambridge) and Prince William on April 29th.

Pippa Middleton donned a Sarah Burton Alexander McQueen gown and her star power shot threw the roof. It seemed like every few days a new crop of photos would turn up.

Now the Middleton family is taking action in Britain against four major publications that have published the images, including The Daily Mail and The Daily Mirror.

The family has filed a formal complaint to Britain's independent Press Complaints Commission.

According to OTRC, the commission will determine whether the publications who published the photos have violated Middleton's privacy, or whether there are any "public right to know" issues which would justify publication. European law protects privacy and free expression, leaving interpretation up to judges to determine which apply.

The topic of intense paparazzi attention and it's negative impact isn't new territory for the royal family. The paparazzi has long been blamed for the death of Princess Diana in 1997.

Although, a new film, "Unlawful Killing" which will show a Princess Diana death photo moments after the fatal car crash, alleges there was a conspiracy.
